Fix NaCl system header files location

NATIVE_SYSTEM_HEADER_DIR is target makefile variable that describes where system headers are located, relative to file system root. Default is /usr/include.

When building a cross-compiler configured using --with-sysroot, CROSS_SYSTEM_HEADER_DIR is constructed from sysroot value followed by NATIVE_SYSTEM_HEADER_DIR.

We don’t have /usr/include on NaCl, so set this to /include.

This only affects configurations that use --with-sysroot, so the actual effect will become visible only when I add --with-sysroot to gcc configuration.
